Su Wantang, a modern and cute social animal, traveled through time and became Shen Chutang, the ugly legitimate daughter of the Prime Minister of Daqi (with a large cinnabar birthmark on her face). Because of her "unlucky" identity, her concubine Shen Yurou and her stepmother Zhou designed to break off the engagement and humiliate her. By chance, they meet Gu Zhaozhi, the helmsman of the Jiangnan Cao Clan (who is close to the Prime Minister because he is investigating the truth about his father's murder), and the two collaborate: Shen Chutang uses modern simple wisdom to resolve the difficulties faced by his stepmother and the provocation of his concubine (such as poisoning and turning the rumor-mongering army into an army).
